Continued Fraction

A fraction with 1 as the numerator and a sum of an integer and another fraction in the denominator.

Find x, y, and z

Given the equation 1/(x + 1/(y + 1/(z+1/4))) = 29/79, x, y, and z are natural numbers.

Value of x in the Equation

After inverting and simplifying, x = 2. Then find the reciprocal of the remaining fraction.

Value of y in the Equation

After finding x and inverting the remaining fraction, y = 1. Then find the reciprocal of the remaining fraction.
